how do you say mountain range in spanish
a series of more or less connected mountains ranged in a line.
If they are not very high, some choices are:
cadena de sierras
If they are high, cadena montañosa describes them better as mountain range.
The Appalachians are a vast range of mountains in eastern North America = Los Apalaches son una vasta cadena montañosa del sudeste de Norteamérica
Thanks. Now I´m going to listen to ¨Blue Ridge Mountain blues¨ & ¨Take me home, country roads¨
From Gran Diccionario Oxford, the fifth meaning for range is
5 (chain) cadena f; a mountain range = una cordillera, una cadena de montañas
